}

Object-safe plugin registered for a layout ID.

Required Methods

fn as_any(&self) -> &dyn Any

Returns this plugin as Any.

fn id(&self) -> LayoutEncodingId

Returns the globally unique layout ID.

fn build( &self, dtype: &DType, row_count: u64, metadata: &[u8], segment_ids: Vec<SegmentId>, children: &dyn LayoutChildren, build_ctx: &LayoutBuildContext<'_>, ) -> VortexResult<LayoutRef>

Deserializes a layout node.

Implementations

impl dyn LayoutVTablePlugin + '_

pub fn is<V: VTable>(&self) -> bool

Returns whether this plugin is vtable V.

pub fn as_<V: VTable>(&self) -> &V

Downcasts this plugin to vtable V.

pub fn as_opt<V: VTable>(&self) -> Option<&V>

Attempts to downcast this plugin to vtable V.

Trait Implementations

impl Display for dyn LayoutVTablePlugin + '_

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for dyn LayoutVTablePlugin + '_

impl PartialEq for dyn LayoutVTablePlugin + '_

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
